Schismatogobius is a genus of fish in the subfamily Gobionellinae. They are native to southern and eastern Asia, Australia and the Pacific Islands. [1] Adults dwell in freshwater habitat such as streams and rivers, where they live along the sand and gravel substrates.
These fish are not always obvious in the habitat, because they are small and cryptic. They lack scales and have variable color patterns, with no two individuals of a given species alike. Compared to those of females, the jaws of males are "hugely large". [1]
The 20 recognized species in this genus are:
Stiphodon is a genus of freshwater gobies. They inhabit swift, clear streams close to the sea and are found in large parts of Asia and Oceania. Many of the 36 currently recognized species have extremely restricted distributions on single islands or even single streams. These are small gobies with bodies squarish in cross section. A female of Stiphodon multisquamus with a standard length of 60.4mm is the largest Stiphodon individual on record.
Rhinogobius is a genus of primarily freshwater gobies native to tropical and temperate parts of eastern Asia. Most are small, streamlined in shape, and often sexually dimorphic. Few are of commercial importance, but R. duospilus is fairly widely traded as an aquarium fish.
Lentipes is a genus of gobies native to fresh, marine and brackish waters of the Malay Archipelago and islands in the Pacific. Its species are typically from fast-flowing streams and some are anadromous.
Mugilogobius is a genus of fish in the family Gobiidae. They are found in fresh, brackish and marine water of the Indo-Pacific region. Several of the freshwater species have highly restricted distributions.
Oxyeleotris is a genus of sleeper gobies mostly restricted to Australia and New Guinea, though some are found in Southeast Asia.
Redigobius is a genus of fish in the goby family, Gobiidae, known commonly as dualspot gobies. They are native to the western Indo-Pacific region, where they occur in estuaries and freshwater habitats just above the tidal influence.
Sicyopterus is a genus of gobies native fresh waters from Madagascar to the Pacific islands.
Sicyopus is a genus of small gobies. Most are native to fast-flowing streams and rivers in Southeast Asia and Melanesia, but S. zosterophorus also occurs in China, Japan and Palau, S. nigriradiatus is restricted to Pohnpei, S. jonklaasi is restricted to Sri Lanka, and S. lord is restricted to Madagascar.
The Gobiiformes are an order of fish that includes the gobies and their relatives. The order, which was previously considered a suborder of Perciformes, is made up of about 2,211 species that are divided between seven families. Phylogenetic relationships of the Gobiiformes have been elucidated using molecular data. Gobiiforms are primarily small species that live in marine water, but roughly 10% of these species inhabit fresh water. This order is composed chiefly of benthic or burrowing species; like many other benthic fishes, most gobiiforms do not have a gas bladder or any other means of controlling their buoyancy in water, so they must spend most of their time on or near the bottom. Gobiiformes means "goby-like".
Pseudogobiopsis is a genus of fish in the goby family, Gobiidae. They are native to fresh and brackish waters of southern and southeastern Asia. The genus is mainly distinguished by the number and arrangement of fin rays and spines, headpores, and sensory papillae, the large mouths of the males, a fleshy or bony flange on the pectoral girdle, and the shape of the genital papilla.
The Gobionellinae are a subfamily of fish which was formerly classified in the family Gobiidae, the gobies, but the 5th Edition of Fishes of the World classifies the subfamily as part of the family Oxudercidae. Members of Gobionellinae mostly inhabit estuarine and freshwater habitats; the main exception is the genus Gnatholepis, which live with corals in marine environments. The subfamily is distributed in tropical and temperate regions around the world with the exception of the northeastern Atlantic Ocean, the Mediterranean Sea, and the Ponto-Caspian region. It includes around 370 species and 55 genera: Wikipedia articles about genera list about 389 species.
Callogobius is a genus of fish in the family Gobiidae found in brackish and marine waters of the Indian and Pacific Ocean.
Eugnathogobius is a genus of gobies native to fresh, brackish and marine waters of the Indian Ocean and the western Pacific Ocean region.
Gobiosoma is a genus of gobies native to fresh, brackish and marine waters of the Americas.
Pseudogobius is a genus of fish in the goby family, Gobiidae. It is widely distributed in tropical and temperate regions of the Indian and western Pacific Oceans. Species occur in freshwater and estuarine habitat types, such as mangroves and seagrass beds.
Pseudogobiopsis lumbantobing is a species of goby from the subfamily Gobionellinae which is found in Java and Sumatra where it occurs in freshwater rivers and streams at altitudes of 5–22 metres (16–72 ft), with substrates made up of sand, gravel, rock, and boulders and where there may be growths of algae and aquatic macrophytes. This species has been traded in the European aquarium trade since 2001.
Sicyopterus stiphodonoides is a species of goby in the family Oxudercidae. It is found in the Solomon Islands and in the Papua Province in Indonesia.
Sicyopterus lengguru is a species of goby in the family Oxudercidae. It is found off Papua New Guinea.
Sicyopterus squamosissimus is a species of fish in the goby family Oxudercidae. It is found off the islands of Sumatra and Java in Indonesia.
